So we don't get to see when will the next spoil of war be ready, the icon isn't darkened either, it just looks like it has all its stacks except the number is "0", had me mess up my ADC's cs more than once because I thought I could execute the minion when I couldn't. (the vfx is fine though)
NappyXIII1 votesHad this same problem. Was playing Poppy support in ranked summoner's rift and noticed this two games in a row. It's only the icon, and only occurs below 1 stack as OP states.
Eselinchen2 votesIn fact, it's not exclusively when the counter's at 0, I made a video showing it wouldn't show the timer even at 1 Stack https://twitter.com/DasEselinchen/status/871783258102616064 It was totally random whether or not it would shown me the remaining time :/
Halego1 votesIt happens with Fervor stacks too. Really annoying when you try to keep it up in lane.
I Love Thresh1 votesThe bug's still present. Gonna bump this every patch til it gets fixed
